:BALL-:ROLLING MACHINE.

Specification of Letters Patent.

Patented Apr. 30, 1918.

Application 1ed August 10, 1914. Serial No. 856,089.

To aU flo/wm. z't 'may concer/n Bc it-lmown that I, CLARENCE H. BAn'roN,a citizen of the United States, residing at Indianapolis. in the countyof Marion and State of Indiana, have invented certain new and usefulImprovements in Ball-Rolling Machines, of which the following is a full,clear, and exact specification.

This invention relates to ball rolling machines.

Twine placed on the market is` made up into balls of definite sizes andshapes. After the balls have been removed from the ball*- ing machinessuch balls do not always presont a smooth surface; that is, some of theturns may be a little higher or lower than the adjacent turns. Theseballs, for commercial use, should be uniform in size and shape, andshould present a smooth hard surface devoid of any irregularities whichwould cause the twine to loosen accidentally.

The main object, therefore, of this invention is to give balls of twinea hard, smooth and uniform surface.

Another object of this inventiongis to pro vide a simple, compact andinexpensive ma chine for automatically feeding said balls thcrcinto,rolling said balls, and automatically discharging said balls.

These and other objects are accomplished by providing a ball rollingmachine having means for feeding the balls into the machine, means forrolling the balls, andmeans for automatically discharging said ballsfrom said machine; balls thus treated being adapted to meet allrequirements of, coxnmercial usage.

The invention is illustrated on the accompanying sheets of drawings, inwhich- Figure 1 is a side elevation of my ball rolling machine;

Fig. 2 is an end view thereof;

Fig. 3 is a sectional view of the same machine taken in the plane ofline 3 3 of Fig. 2; and

Fig. 4 is a detail view of part of the c0ntrolling mechanism. 1

The various novel features of my inven-4 tion will be apparent from thedescription and drawings, and will be particularly set forth in theappended claims.

This balling machine includes a. main frame 10 havmg aguiding run-way 11in which the balls` roll when discharged from the operating rollers tobe referred to later.

posed between bracket 21 and fork 30 tendengagement wit Secured to thismainframe is a supplemental frame 12 in which two shafts 13 and 14 aremounted. Mounted upon one end of shaft'13 is a beveled gear 15, (seeFig. 2), meshing with a beveled gear 16 mounted upon a ower shaft 17. Onthe opposite end 0f t e shaft 13 issecured another beveled gear 18meshing with a beveled gear 19 secured to a shaft 20 supported inbrackets 21-and 22. Also secured to the shaft 20 is a beveled gear 23meshing with a beveled gear 24 on one end of the shaft 14. Secured tothe shaft 13 is a roller 25, and se# cured to the shaft 14 is a roller26. Intermediate the beveled gears 19 and 23 and mounted on the shaftare two parts 27 and 28 of a clutch,the part 27 being rotatably securedto the shaft and slidably mounted thereon, and part 28 bein loose onsaid shaft. The clutch art 27 ias a groove 29 for the reception o a-fork 30 secured to a rod V31 slidably mounted in the brackets 21 and22, there beingv a spring 32 inter-4 mg to keep the 'clutch parts 27 and28 out of engagement with each other. Formed integrally with clutch part28 and being loose on the shaft 20 is a worm4 33 meshnvF with al wormgear 34 mounted on one end of a small vshaft 34" to the other end ofwhich is secured a spur gear 35 which meshes with a spur gear 36 looselymounted on shaft 13. ,f

l Pivotall lsecured at 37 to the frame' 12 is a bell eran lever 38, toone arm 39 of which vis secured one end of a-spring 40, the'other end ofwhich is secured to bracket 21, which spring tends to hold the rojection41 .of arm' 42 of the bell crank ever in engagement with'a portion ofthe fork 30 to lock the clutch` parts 27 and28 in en gement with eachother in opposition to t e action yof spring 32. vThe arm 39 `of thebell crank lever` lies in the path of a projection 44 formed integrallywith the worm gear 34. 10o

This pro'ectlon engages the arm 39 of the bell cran lever for swingingthe lock or proection 41 out of engagement with the for 30 to permit theslpring 32 to separate' clutch part 27 from c 'clutch part 27.eriodicallys thrown into the clutch part 28 by a' r cam 45 formed on onesideof a ratchet wheel 46, which ratchet wheel is actuated by aneccentric 47 mounted, on the shaft 20, 110

utclifp'art. 28. The 105 and working in an elongated opening 48 of aswinging arm 49 pivotcd on a stud 50 secured to bracket 22. This arm 49is provided withv a awl 51 which transmits motion in one direction tothe ratchet wheel from the eccentric 47, said arm also having anotherpawl 52 for preventing said ratchet from rotating in the op ositedirection.

Secured to one side o the spur gear 35 is a crank shaft 54 to which isconnected a link 55 having an elongatedopening 56 for slidably receivinga rod 57 mounted in arms 58 pivotally connected to a support 59. lfVhenthe link 55 is actuated in an upward direction the rod 57 is engaged bythe bottoni ot the opening 56, forcing the arms 58 upwardly, and alsothe roller 60 journaled in the ends of said arms. At the same time arm61, which is pivotally mounted'on the shaft 14 and connected toone ofthe arms 58 by link 62, is also raised for feeding a ball from thesupply inclined run-way 63 into the machine and between the rollers 2526 and 60.

FThe balls are discharged from between the rollers 25, 26and 6()l b anarm '64 loosely mounted upon the sha t 13 and actuated by a pro'ectlon65, formed integrally on one side o the spur gear'36, sai projection 65engaging al projection 66 on said arm 64, the arm 64 rotatin in acounterclockwise direction for li ing the balls from between the rollers25 and 26, the loller 60 at that time being in a raised position. Aprojection 67 is also formed integrall -with the spur gear 36 forlimiting the alling movement of the arm 64 after it has passed throughan angle of 180 from the position shown in Fig. 3. The operation of themachine as a whole will now be considered.

Let it be assumed that the parts are in the position shown in Fig. 1 ofthe drawings,

there being a ball 69 between the rollers 25, 26 andV 60, the rollers 25and 26 being rotated continuously through the transmission connections:from power shaft 17, and roller 60 being rotated intermittenti throughthe rotation of the ball 69, whic is rotated by the rollers 25 and 26.During this rotation of the rollers, which receive their motion throughshaft 20, the ratchet wheel 46 'is also being slowly rotated throughsaid shaft 20 and eccentric 47. The rolling of each ball 69 between therollers is of comparative long duration, corresponding to about 340 ofmovement of the ratchet wheel 46. During the remaining 20 of movement ofthe ratchet. wheel 46, the clutch parts 27 and 28 are thrown intoengagement with each other for causing the ejection of the ball betweenthe rollers and the feeding in of another ball, the clutch parts thenbeing thrown out of engagement with each other. This closing of theclutch causes the lock the clutch parts 27 and 28 into engagement witheach other in opposition to the action of the spring 32. After thistakes place the cam 45 passes out of engagement with the rod.31. As thespur gear now continues to rotate with worm gear 34the spur lgear 36 isalso caused to rotate, the projection 65 eventnall passing intoengagement with the projection 66 on the arm 64 for raising the said armto eject the ball 69 from between the rollers 25, 26 and 60, the roller60 having been raised sufficiently for this purpose in the meantime bythe link 55 and pin 57 engagingv the bottom portion of the elongatedopenlng 56 in said link. As the ball 69 is ejected from between therollers 25 and 26 the member 61 passes into engage ment with the nextball 75 on the supply run-way 63 to move said next ball into positionbetween the rollers 25 and 26. As the machine continues to operate theroller 60 and member 61 are gradually lowered, due to their own weight.

When the worm gear 34 has completed a revolution the projection 44 againpasses into engagement with the arm 39 of the bell crank lever 38 forforcin the lock portion 41 out of engagement with the yoke 30 to permitthe Spring 32 to separate the clutch parts 27 and 28, whereupon the Worm33,

, worm gear 34, spur gears 35 and 36 are ar rested from furthermovement. The ball just placed between the rollers of the machinecontinues to be rolled until thel cam 45 and ratchet wheel 46 makes acomplete revolution, and cam 45 passes into engagement with the rod 31to again throw clutch part 27 lnto en agement with clutch part 28,whereupon t e above described opera.- tion is repeated. It is seen,therefore, that the balls are automaticall fed into the machine andbetween the 4rol ers, automaticall rolled to ive them a hard, smooth andunlform sur ace, and automatically discharged from between the rollers,rendering the operation simple and inexpensive.
